SOMI u need to be very care full with these things.. u know every discovery has to be done by them only ...did u ask urself why.. its because they have a world wide media coverage.. we have professors here..what did they discover anyway.. i know they have done something... but who knows anything about TBC, ITV, C2C, CHANEL5, CHANEL 10. its me and u they dont know about this rabish... who told u that the americans visited the moon? its themselves through CNN, its their media but widely watched...if u need proof then they will prove but i know TBC WILL NOT DISAPROVE WHAT THEY SAY brother wake up...

Ilizaniwa kwamba Asteroid 1997 XF11 had a small but non zero chance of hitting earth in 2028, but this is now corrected to a zero chance.

The Asteroid Apophis was thought to have a non zero chance of hitting the earth in 2029, but this is now reduced to zero, there is still of concern about a slightly more chance of Pophis hitting the earth in it's next sojourn in 2036

The asteroid 2006 HZ51 was supposed to hit us in June 2008, obviously it didn't.

There is a probability of 1 in 800,000 for an extinction level event (i km or more) asteroid to hit the earth in any given year.This means this only happens on average once every 800,000 years. A 200 metres object strikes once every 100,000 years and a 40 metres object strikes once every 1,000 years

The U.S Congres directed NASA to identify by 2008, 90% of all asteroids and comets more than one km (low probability and high consequence) in diameter with orbits approaching earth.By 2004, the US was the only nation in the world doing anything about the possibility of asteroid impacts, I am not sure if this has changed since then.

On June 30th 1908 in Tunguska Siberia, an asteroid about 55 metres fell on earth and detonated above the surface there, with a force of 800 Hiroshimas, similar to a magnitude 8 earthquake, eight hundred square miles of Russian woodland were incinerated in seconds

I am looking for a table with the names, periodicity and impact probability of all known asteroids posing a threat.
